vesters, and more especially to a mechanismso arranged that itcan be operated by the driver from his seat without checking the machine and while the machine is in motion; and

my object is to construct such mechanism so as to be light, inexpensive, and durable, and so as to be employed to elevate the machine over low obstructions in the grain instead of driving around such obstructions. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a top plan view of a harvester provided with my improvements, with the master-wheel shown in section and partly broken away and part of the plate D and toothed rim are also broken away. Fig. 2 is a view from the rear of part of the machine with the master-wheel, the bar K, and the toothed rim shown in section. Fig. 3 is aside or face view of the parts shown in Fig. 2, looking to the left from line 1 1. Fig. 4 is a detail view of a bracket. Fig. 5' is a detail sectional view looking to the left fromline 2 2, Fig. 10. Fig. (3 isa detail view of the bracket provided with the locking-dog.

The upper end of the plate D is extended and bent to a horizontal position, forming the projection D To said projection D is seen red the bracket Z), encircling the post (1 and having'a vertical movement on said post (1.

fdesignates the finger-bar, of the ordinary 2 form, provided at its front edge with guards f and inner shoe f f is an inward extension extending to the rear edge of the plate D with its front flange 9 cut off, as shown to the left of Fig. 10, to be adjacent the rack 64, with the vertical angle or web extending past the plate D and bent forward atf on the back of said plate D. (See Fig. 1.)

h designates a bar secured at one end to the shoe f and with its other end extending to and past the front edge of the plate D, with 'its end turned rearward at f on the back of the plate D.

I designates a bracket extending over the bar h, with its end I turned down and secured to the bar h adjacent the bar (1 with its other end extending to the rear adjacent the rack a,with its end I projecting beyond said rack o and turned down, as shown in Fig. 4, so as to form, in connection with the bracket 1 a bearing for one end of the shaft J.

K designates a cross-bar extending from the bar it to and over the extension f, with its front end K bent upward on the bar It and secured to said bar a suitable distance grainward from the plate D (see Fig. 1) and secured to the extension f by the rivet K and its rearward-projecting end isbraced in position by the brace K.

K designates a part of the bar K turned stubbleward toward the master-wheel A to furnish a support for the fore end of the lever L. On said bar K is located the post d, with its lower end secured to the bar h and by the bracket K to the bar K. (See Fig. The upper end of said post cl is braced in position by the braces on and n. The brace m is secured with its lower end to the vertical flange of the shoe f and with its upper end to near the upper end of the post (Z, and the brace 01 is secured at its upper end to near the upper end of the post cl and with its lower end to the bar K with the rivet K (See Fig. 3.)

P design ates a bar secured at one end to the post d beneath the brace m and above the bracket b, extending rear vard with a short crook downward, as shown in Fig. 3. and secured to the brace 01 by the bracket 01. To the rearward-projecting end is seen red the bracket P a proper distance from bracket n, so as to receive the rod j in a vertical position.

To near the rear end of the bar Pis pivoted a thumb or hand latch P by the stud P for the purpose hereinafter stated.

a designates a shaft in a vertical position and provided near its lower end with a bearing a secured to the bracket I, and a collar a secured to the shaft a just above the bearing (t and a pinion a below the bearing a, thus preventing any endwise movement of the shaft 0. in the bearing a". Said shaft a extends, with its upper end, through the bearing a, secured to the projection D and projects, with its upper edge, through a perforation in said projection D The shaft [L3 is provided with a keyway e and a bevel-pinion a above the bearing a in position to engage with the toothed rim B, and provided with a key to engage the key- Way a to prevent the bevel-pinion a from rotating on the shaft a a is a bracket secured at its ends to the projection D and curved over the bevel-pinion, as'shown in Fig. 3, to prevent its upward movement on its shaft a J designates a shaft journaled with its grainward end in a bearing J secured to the brace 02, (see Fig. 3,) and a bearing near its other end in the bracket I and provided with a pinion J? on its (said) projecting end in position to engage with the rack (1 and a pinion J 2 near its center.

L designates a lever pivoted on the shaft J between the bracket I and the pinion J (see Fig. 1,) and provided with an arm L,

pivoted on the shaft J on the opposite sideof the pinion J with its other end projecting rearward and secured to the lever L, thus preventing the rear end of lever L from having any lateral movement. Said lever L and arm L are also employed as a brake, as hereinafter described.

L designates a dog pivoted to the lever L and engaging with its free end with the pinion J To near the free end of the dog L is pivoted a rod L connecting the dog L to the handlatch P by which the dog L can be disengaged from the pinion J L designates a rod pivoted to the lever L a suitable distancev from the pivoted end of the lever L and provided with a stud L about six oreight inches from its pivoted end and in position to be engaged with or disengaged from the toothed rim B. NVhen said rod is not in operation, it is allowed to rest in ahook P formed on the end of the bracket P, as shown in Figs. 1 and 2.

z" designates a bracket formed about as shown in Figs. 6 and 9, and provided with a locking bar or dog *6, loosely secured to the bracket 1" and provided with a large eye 0 to receive the rod j, and an extension 0 (see Fig. 8) to engage between the pinions J and J so as to act as a dog to lock said pinions in place. (See Fig. 5.) The upper portion of the bracket 2" is curved forward at i to provide room for the rod Z when the lever L is operated. The free ends of the bracket 2" are perforated to receive the rodj. Said rodj is curved or crooked about as shown in Fig. 7 and extends through the free ends of the bracket i and the dog 1', extending down on the grain side of the arm L, while the bracket t" extends down on the opposite side of the lever L, so that when the rodj is turned onehalf round, so as to bring the crooks j andj grainward and the crook fstu bbleward against the arm L, the arm L and lever L willbe drawn together against the pinion J clamping said pinion, and thus acting as a brake on said pinion, so as to lower the machine gradually. When the rod j is turn ed in position, as shown in Figs. 1 and 2, the crookj projects rearward, thus disengaging the dog 1' from the pinions J and J, and when moved in the opposite direction, as shown in Fig. 3, the crook jprojects forward, thus allowing the dog '5 to engage with the pinions J and J. Said dog i is caused to engage with the pinions by a spring i secured to the bar K and passing with its upper end "against the free end of the dog 1'. The eye 0 in the dog 2' is of sufficient size to allow the dog the proper amount of play. The lower end of the rodj extends through a bracket i secured to the lower side of the bar K (see Fig. 3) and provided with a pin or not 1' to prevent its disengaging from 7 said bracket 2' and said rod extends with its upper end through a bracket P and is provided with a handle 1' by which it is operated.

J designates a short shaft journaled in a long bearing J with its stubble end projecting through said bearing and provided with a pinion J on said projecting end in position to engage with the pinion J and connected with its other end by a universal joint to the shaft R, which is in turn connected by a universal joint to the shaft R. Said shaft R has near its stubble end a bearin g R secured to the rear and lower flange of the finger-bar f. Said shaft R extends along the rear flange to the outer end of the finger-barf, with a bearing near its outer end in the bar 2, secured to the finger-barfand projecting to the rear.

25 designates a pinion secured on the shaft R adjacent the outer side of the bar t.

o is a segment pivoted at its rear to the rear end of the bar If and projecting forward in position to engage with the pinion 25 IIO '0 is a stud or bolt secured in the segment 1) and forming the axle for a grain-wheel.

t is a brace secured to the rear end of the bar If and to the finger-bar f.

t designates the usual grain-board secured to the finger-bar f by the bracket '15" and out out to provide room for the pinion t and with its inner edge t projecting past the inner side of the segment n.

a; designates a plate secured to the outer side of the grain-board, providing a support for the outer end of the shaft R and extend ing toward the rear past the outer edge of the segment 1), thus furnishing a guide for said segment 1 In Fig. l the grain-board t is partly broken away to show the pinion P.

In raising the machine while in motion the driver moves the lever 2' in position, as seen in Fig. 3, and then moves the rod L' in position, as seen in Fig. 3, engaging the stud L with the toothed rim B, by which said rod L will be elevated, thus elevating the lever L and turning the pinion J forward by means of the dog L Said pinion J is secured to its shaft J, and thus turns the pinion J in the same direction, and, it being in engagement with the rack a, will elevate the inner side of the machine, and the pinion Jibeing in mesh with the pinion J, will rotate the shafts R and R, by which the outer end of the machine is elevated. \Vhen the lever L is elevated to a suificient height, the stud L is disengaged from the toothed rim B, and the lever L is allowed to drop down in position, as seen in Fig. 3, the dog i engaging between the pinions J and J to prevent their back ward movement. Then the stud L is again engaged with the toothed rim B. Said operation is repeated until the machine is elevated to the desired height. The lever L is extended to the rear a proper distance, so that the machine can be elevated by hand while at rest, if so desired.

To lower the machine, the driver moves the lever 2' in position, as seen in Fig. 1, thereby disengaging the dog and clamping the lever L and arm L against the pinion J when he grasps the hand-latch P pressing it against the bar P, thus disengaging the dog L from the pinion J when'he will slaeken the lever 2' to allow the pinions to rotate backward, thus allowing the machine to lower. hen the machine is thus lowered to the desired level, the hand-latch P is released, allowing the dog L to engage with the pinion J and lock said pinion in place. The lever 77 can be moved in position as seen in Fig. 3 or left in position as seen in Fig. 1.

I do not broadly claim the combination of a traction-wheel to raise the machine, nor broadly the combination of a vertical plate provided with a rack. Nor do I claim, broadly, the raising and lowering of both ends of the machine simultaneously; but
